Connectors for assembling shipping containers

ABSTRACT

A series of connectors for connecting panels of a shipping crate or box together. The invention will allow the user to make a box from a kit. A set of uniquely shaped corner pieces that will accommodate the sides, top and bottom of the structure will be used and provide the framework for the finished product. Because of these corner pieces the finished crate or box will be as strong as a box that is made by a skilled carpenter. Intermediate reinforcement pieces are also disclosed.

BACKGROUND OF THE INVENTION

A. Field of the Invention

This invention relates to the field of packaging and, more particularly, relates to apparatus for attaching panels of a package, box or container together to form an article shipping enclosure. The invention permits the easy formation of an extremely strong box in any size or shape in which to ship an item without undue cost or difficulty.

B. Prior Art

Articles that need to be shipped come in various shapes and sizes, and it is not uncommon to have odd-shaped items that need to be shipped. These types of odd-shaped items are difficult to ship because of their unique geometric structure. Currently a specific box or crate must be custom made to house the uniquely shaped item if the item does not fit into a pre-existing sized box. Custom manufacture of shipping boxes, whether of cardboard, wood or of any other material, is costly and time-consuming, both in terms of material and labor. Ordinarily a carpenter would need to make the box from wood, which may take hours, even with a skilled carpenter doing the work.

Conventional shipping crate building methods and apparatus result in exposed staples, screws and the like extending from either the inside or outside of the crate, which may damage the contents or injure a handler. As a result, many shipping outfits refuse to accept freight which is improperly crated, or which has been crated by methods, and using apparatus, which do not meet the strength and safety criteria of the shipper. Many individuals seeking to ship freight do not have the wherewithal to properly construct a crate which will meet the specifications of the shipper.

Even if the crate is insured prior to transit, it still must be inspected when it reaches its destination if it has been damaged during shipping to determine if it was indeed crated properly. If not, insurance coverage may be denied.

There are many prior art references directed to crate or box making kits, including collapsible plastic crates. A representative example of this type of device can be found at Sunus, U.S. Pat. No. 4,789,075.

Another example of a metal shipping crate can be found at Dunn, U.S. Pat. No. 6,726,041, and a returnable crate is found at Grigsby Sr., U.S. Pat. No. 6,585,126.

None of the prior art references use unitary box panel connectors to secure the various pieces that form the sides, top and bottom of the crate. The connectors permit the user the unique ability to form the structure in any shape or size to custom make a box or crate to fit specific shipping needs.

Therefore, a need exists to provide a simple apparatus for assembling shipping crates/packages/boxes and the like, which can be combined with crate/package/box side, top and bottom panels of any dimensions to construct shipping crates of any sizes and proportions.

It is, therefore, an object of this invention to provide a simplified shipping box and crate assembly kit, apparatus and method.

It is also an object of this invention to provide a simple apparatus for creating shipping boxes and crates of any sizes but which can withstand the rigors of typical freight handlers.

It is also an object of this invention to provide a cost efficient apparatus, system and method for constructing shipping boxes and crates.

These and other objects, features and advantages of the present invention will become apparent upon reading the following detailed description of the disclosed embodiments of the invention, in conjunction with appended drawings and claims.

BRIEF SUMMARY OF THE INVENTION

This invention is directed to a device to make a crate or box specific to an individual's shipping needs. A set of connector pieces will be used to join the side, bottom and top panels of a box in order that the assembled box can support the weight of the cargo inside the box and also allow the box to retain its shape.

A box or crate will have a defined top, defined bottom, and defined sidewalls. With this invention, a set of corner pieces, or edge pieces, or any combination of the two, will be used to connect the panels so that an individual can custom make his or her box or crate to fit a specific need. The exact size of the box that will be made will depend on the dimensions of the sides, top and bottom of the box, and the size of the box that will be made using the connectors of this invention has essentially no limit. In fact, in certain circumstances it may be desirable to use any of the known banding techniques, wherein a metal or other high tensile strength strap is placed around four sides of the crate or box being assembled and pulled taut there around.

This is a device, that is a kit for making a uniquely shaped crate with which an individual can custom make a box or crate to fit and address those particular needs in a matter of minutes without the necessity of hiring a skilled craftsman. The finished crate or box will be as strong as the box or crate that is made by the skilled carpenter and will accommodate the item to be shipped. Additionally, the crate or box may be reusable depending on the condition of the box material after the box has been shipped. The box may also be made without tape.

A unique set of corner pieces are disclosed. Corner sections of each of the sides, top and bottom of the crate or box will fit into corresponding channels defined by the corner pieces. Fasteners to secure the sides, top and bottom of the structure to the corner and side connectors will also be provided. This may be accomplished with staples, screws, bolts or adhesive, to name a few examples.

Additionally, a set of reinforcing members or strips may also be used in the interior of the box (i.e. between corners along adjacent edges of the side and the top and bottom) to secure the sides to the top or bottom and provide additional support and strength for the box or crate. These reinforcing members may be custom made to fit a particular need by simply snipping or cutting off a desired length of reinforcing member and placing it/them in desired locations on the box or crate either alone (i.e. without the use of corner connectors) to supplement the corner connectors

DETAILED DESCRIPTION OF THE EMBODIMENTS

This device is a kit to make shipping cartons or boxes specifically designed to ship any uniquely shaped items. Boxes to ship devices are common in the prior art. However, there are standard-sized boxes that are used to ship letters, posters, and the like. The difficulty arises when a uniquely shaped object must be shipped that does not fit one of the standard boxes that currently exist.

A carpenter or other skilled craftsman must be employed to make a specifically designed box in order to ship the item. This is, of course, costly in terms of labor and material. It would be helpful to have a kit from which individual boxes of virtually any size or proportions can be made using a plurality of standard corner and side connectors.

Additionally, because of security concerns, the interior contents of the box or crate may be visually examined by the shipper or government authority. It is important to easily gain access to the internal contents of the box or crate and then be allowed to reseal the box or crate. This kit will allow an individual to perform that particular function.

A typical shipping container or box suitable for use with the teachings of this invention is shown in FIGS. 12A-14B and comprises a top 2, bottom 3, and sides 4, 5, 6 and 7. They may be joined at the eight corners by eight corresponding corner connectors, which may be any one of the various embodiments of corner connectors disclosed herein, or modifications thereof which will occur to those of skill in the art. Additionally, or alternatively, intermediate panel edge connectors such as any of the side connectors disclosed herein may be employed anywhere along the edges E of the shipping container to provide primary (if used without corner connectors) or additional intermediate (if used together with one or more corner connectors) support and strength. In this manner, standard wood or cardboard pieces can be used to form a box to fit the specific need of the consumer.

As depicted in FIG. 1A, a first embodiment of this invention is comprised of a side connector piece 10. The side connector piece 10 has a pair of channels 12, 22 which define an outside edge and an inside edge. The side connector pieces may be made in any of several different designs such as those depicted in FIGS. 1-5, and may be of any length.

The top, bottom and side panels that will be used to form the box or crate will be inserted into these channels such as depicted in FIGS. 12A-14B. It is to be understood that boxes of any configuration, such as pentagons, octagons, triangles, etc., may be assembled using the teachings of this invention. Modifications will have to be made to the connector members of this invention as will occur to those of skill in the art to accommodate angles between top, bottom and side panels which are other then 90°/right angles.

Channels 12, 22 are defined by respective sidewalls 14, 16, and 24, 26. The channels of any particular configuration of edge or corner connector may be of different length. Also, outer sidewalls 14, 24 may be hinged or articulated to permit the use of adhesive strips or toher adhesive material 15 that is secured to the interior surface of the sidewalls 14, 24. Adhesive material 15, if in the form of an adhesive strip, is configured so that a non-adhesive backing strip is peeled back at the corner and then secured to the side, tops or bottom panel that forms the box.

The panels that form the box will be placed within the channels 12, 22. The material which the panels are formed of may be plastic, wood, steel, aluminum, cardboard, etc, and will be dictated by the item that is to be shipped as well as the cost of the panels and cost to ship the item. Additionally, the connector members may preferably be constructed of plastic, graphite, metal or any other suitable material. It must be strong enough to support and form the box while at the same time supporting any weight that is to be applied to the box. Although the corner pieces (and, optionally, the side pieces) are used to make the box or crate, the box or crate may be made without the use of tape.

The sides 4-7, top 2 and bottom 3 of the box or crate can be varied by cutting the sides, top and bottom to the length and width that is required by the user. Depending on the condition of the box material the box may be reusable.

Additionally, there may be other alternative embodiments of the side and corner connectors which will occur to those of skill in the art, and while the box or crate will have the general appearance of a crate or box the side and corner connectors vary such as depicted in the drawings.

The box is formed by placing any one of the corner connectors depicted in FIGS. 7D, 8D, 9D, 10D or 11A-11D, as an example, on the corners where the side panels 4, 5, 6 and 7 will be. Each box or crate will have a defined top and/or a defined bottom as well as three, four or more sides. The sides do not necessarily need to be of equal width or length.

The corner connectors are placed on the corner of side, top and bottom panels 2-7 such that corresponding corners of the sides, top, and bottom of the box will be placed in the channels 12, 22 and 32. Additionally, there may be one or more adhesive reinforcing strips 15, 45, 115 & 135 placed on the inside surface of the sidewalls 14/24, 44/54, 74/84, 102 and 134 (or on the corresponding flexible members 25, 55, 85, 125 and 145) to secure the top to the sides and the bottom to the sides of the box. The reinforcing strips may be made by simply cutting the strip to a specific length and inserting the strip into the sidewall.

Additionally, the panels 2-7 may be secured within the respective channels by fasteners F such as staples, nails, screws or the like as depicted in FIGS. 15-19. The fastener body may extend through sidewalls 16, 26, 46, 56, 76, 86 and/or 104 to the hollow section 8, 48, 78, 112, 168, 258, 298 This will protect the goods inside the box from being damaged because there will be no possibility that the end of the fastener would strike the contents of the box or crate because protective walls 28, 58, 88 and 118, 178, 228, 248 will prevent the fastener from coming in to contact with the article being shipped.

Additionally, the sides may be secured with adhesive for additional support.

FIGS. 4A-4D represent another side connector embodiment 100 showing a single channel 106 and having an open space or shoulder 110. Box top or bottom panel 2 or 3 will be placed directly on shoulder 110 and then secured to the shoulder by using a fastener F such as a screw, bolt, nail, staple, rivet, adhesive, or the like. The other portion of the box or crate will be inserted into the channel 106 as discussed above, and may be held in place therein with a fastener.

FIG. 10D shows a corner connector in accordance with this fourth embodiment of the invention, as discussed in further detail below.

Referring now more specifically to the drawings, FIGS. 1A-1C and 6A-6C show a first embodiment of an intermediate side connector 10 comprised of first sidewalls 14, 16 which define a first channel 12, second sidewalls 24, 26 which define a second channel 22, and a barrier wall 28 connected to first and second sidewalls 16, 26 to form an interior space 18. First channel 12 is adapted to receive an edge portion E of a top panel 2 or side panel 4, 5, 6 or 7 of a shipping box as shown in FIGS. 12A-14B.

FIGS. 11A-11B show the first embodiment of the connector in the form of a corner connector 10′ which incorporates all of the elements of connector 10 shown in FIGS. 1A-1C and 6A-6C, and further includes third and fourth sidewalls 34, 36 which define a third channel 32.

FIGS. 2A-2C and 7A-7C depict a slightly modified version of a side connector which can easily be modified to form a corner connector 4′ shown in FIG. 7D. In this embodiment, channel 42 does not extend below sidewall 56. As shown in FIGS. 7B and 7C, sidewalls 44 and 54 can be hinged, as by the use of a length of one-sided adhesive tape, or any other flexible material adhered to the outer surface of sidewalls 44, 54. Adhesive material 45 may then be applied to the box panel-facing side of sidewalls 44, 54, which will adhere to the particular box panels situated within channels 42, 52 to strengthen the connecting therebetween.

FIGS. 6A-6B and 7A-7C depict a slightly modified version of a side connector which can easily be modified to form a corner connector 40′ shown in FIG. 7D. In this embodiment, channel 42 does not extend below sidewall 56. As shown in FIGS. 7B and 7C, sidewalls 44 and 54 can be hinged, as by the use of a length of one-sided adhesive tape, or any other flexible material adhered to the outer surface of sidewalls 44, 54. Adhesive material 45 may then be applied to the box panel-facing side of sidewalls 44, 54, which will adhere to the particular box panels situated within channels 42, 52 to strengthen the connecting therebetween.

As can be seen in FIG. 7D, corner connector 40′ is essentially identical to side connector 40, with the exception that a third channel 62 is defined by third sidewall pair 64, 66. Sidewall 66 is connected to sidewalls 42, 52 and barrier wall 58 along peripheral edges thereof, similar to the configuration discussed with respect to FIG. 11A.

In this embodiment, a second connector section 100 is integrally attached to the connector segment 100 shown in FIGS. 4A-4C and 10A-10C. Preferably, but not by way of limitation, corner connector, 100′ is formed out of a flat piece of stock material in the shape shown in FIG. 10E. Corner connector 100′ is, thus, upon being formed into the shape shown in FIG. 10D, a mirror image of connector 100 shown in FIGS. 4A-4C and 10A-10C. When used, a first panel side is placed within first channel 106, a second side panel is inserted within second channel 106′, and a top or bottom box panel 2 or 3 is placed upon shoulder 110 in substantial registry with the upper end 113 of sidewall 104.

One or more fasteners may be placed through top or bottom panels 2, 3 and through shoulder 110 into space 112, where they are protected by barrier wall 118 from contacting the item within the shipping box, as shown in FIGS. 18A and 18B. As shown, additional fasteners F may be placed through side panels 4, 5, 6 or 7, the ends of which should also rest within space 112.

FIGS. 18C and 18D show the embodiments corresponding to FIGS. 4C and 4B, respectively, having box side panels 4, 5, 6 or 7 inserted within channel 106 and top or bottom panel 2, 3 resting against shoulder 110. Top or bottom panel 2, 3 may be retained against shoulder 110 by any suitable means such as fasteners F, adhesive, or the like.

FIGS. 20A and 20B depict a modified form of the side connector of this invention, which includes a first channel 162 defined by outer end and inner sidewalls 164, 166 respectively, a second channel 172 defined by outer an dinner walls 174, 176, respectively, and an end wall 169 at the base of channel 172 (although end wall 169 may be positioned at the end of channel 162 in the alternative), and a barrier wall 178 defining a fastener and protection space 168. As can be seen from these figures, the side connector is manufactured from a single piece of (originally flat) material such as metal, and bent into the form shown. As discussed above and in connection with essentially all embodiments of the invention, the connectors disclosed herein may be formed by injection molding, extrusion, or any other manufacturing technique which will occur to those of skill in the art.

FIGS. 20C and 20D depict a still further modified embodiment of the side connector 180 of this invention, comprised of a first channel defined by outer end and inner sidewalls 184, 186, a second channel 192 defined by, outer and inner sidewalls 194, 196, and an end wall 199. Again, it can be seen that the embodiment of FIGS. 20C and 20D can be formed by bending/stamping a single flat piece of material, or may be extruded, injection molded, etc.

FIGS. 20E and 20F disclose a still further modified form of the side connector 200 of this invention, comprising a first channel 202 defined by outer and inner sidewalls 204, 206, a second channel 212 defined by outer and inner sidewalls 214, 216. This embodiment likewise may be formed by a single piece of bent material or may be injection molded, extruded, or the like.

FIGS. 21A-21C depict a still further modified embodiment of the invention.

FIGS. 21A and 21B depict a side connector and FIG. 21C depicts a corner connector similar in construction to a pair of side connectors connected to each other. The angle between the two is 90° shown in FIG. 21C, although that angle may be more or less than 90° depending upon the angle of the corner of the crate being made.

The connector of this embodiment includes a channel 222 defined by outer and inner sidewalls 224, 226, a top sidewall 230 adapted to receive a crate panel in coplanar fashion thereon, and a barrier wall 228. In use, a first panel will be inserted into channel 222, a second panel will be placed coplanar with top sidewall 230, and fasteners placed there through and through sidewalls 224, 226 and 230 and 232. Sidewalls 226 and 232, along with barrier wall 228, define a space 238 in which the sharp ends of fasteners (not shown) can reside, so that they are protected by barrier wall 228 from contacting the contents of the crate.

FIG. 21C shows the corner connector corresponding to the embodiment shown in FIGS. 21A and 21B, the second section thereof defining a second channel 242 defined by outer and inner sidewalls 244, 246, a top sidewall 250, a barrier wall 248, and an inner sidewall 252. It will readily occur to those skilled in the art that a second panel section can be inserted into channel 242, and the same panel section of the crate that will mate with top sidewall 230 will also mate with top sidewall 250 of the other side of the connector 240, and fasteners placed through both panels to secure them to connector 240.

FIGS. 22A-22C depict a further modified embodiment in this invention.

FIGS. 22A and 22B show a side connector 260 which defines a first channel 262, which is defined by outer and inner sidewalls 264, 266, a top sidewall 270 and a panel end wall 272. A barrier wall 268 and barrier space 278 are also employed. In use, a first crate panel is inserted into channel 262 and a fastener placed through sidewalls 264 and 266, and a second crate panel is placed in coplanar orientation on top sidewall 270. The side edge of the panel (not shown) may be placed in abutting relationship with sidewall 272 for added stability.
